In Xi 'an, Shaanxi Province, a confirmed case was only affected by one mouthful of sputum. The reason is that this person was infected because he didn't wear a mask when traveling. Here, I also suggest that you strengthen personal protection. Omicron is highly contagious and will have a great impact on people's health invisibly. At present, there are Omicron mutants in many places in China, and this phenomenon also exists abroad. This strain is 70 times faster than the original strains in Bita and COVID-19. As long as it has been in contact with confirmed cases, it is more than 85% likely to be infected.

1. How contagious is the Omicron strain? The original strain in COVID-19 is highly contagious. The infectivity of the mysterious clone is 70% higher than that of the original strain. You can choose to consider it. How terrible is this? Omicron is terrible. As long as you have chatted with the confirmed case or had some physical contact, you may be diagnosed. The confirmed case of Xi in Shaanxi Province was because he didn't wear a mask when he was walking outside. The sputum from the last confirmed case was infected. So through here, we can also find that it is very terrible. Here, if you want to travel, you must wear a mask whether you walk or do anything.

Second, how to protect it? Wearing a mask is something everyone should do. If you don't wear a mask, it will be seriously affected. Compared with Delta strain, Omicron strain will be more terrible, and Omicron strain is also very cunning, and a little carelessness will easily lead to infection. Although there is no specific medicine now, as long as everyone can take protective measures, nothing will happen.

Third, summarize. The epidemic situation in Xi City, Shaanxi Province is very serious. It is also dangerous to go out for a walk without wearing a mask. We must keep these things in mind, don't always think that COVID-19 is far away from us, and don't gamble with our lives.
